We have just released Go versions 1.19.3 and 1.18.8, minor point releases.
These minor releases include 1 security fixes following the security policy:
syscall, os/exec: unsanitized NUL in environment variables
On Windows, syscall.StartProcess and os/exec.Cmd did not properly check for invalid environment variable values. A malicious environment variable value could exploit this behavior to set a value for a different environment variable. For example, the environment variable string "A=B\x00C=D" set the variables "A=B" and "C=D".
